In other words, you received 50 credits when you moved from Hack to Amateur. Then other 100 credits when you moved from Amateur to Pro. Therefore, you've earned 150 credits or $1.50 (as it shows in earnings). If you enter ready-go's or win credits from entering tournaments it will reflect on your "career earnings". As far as transferring these credits... you've already received them... so transferring is not an option.
Unfortunately, they don't keep track of match play challenge earnings..... which would be nice... any idea if that will ever happen WGTicon?
